# Phyllome OS
Phyllome OS is a [Fedora Remix](https://fedoraproject.org/wiki/Remix) designed to leverage [hardware-assisted virtualization](https://wiki.phyllo.me/virt/lexicon#hardware-assisted-virtualization) and [paravirtualization](https://wiki.phyllo.me/virt/lexicon#paravirtualization) to make it easier to run virtualized operating systems locally.
Phyllome OS uses the [automated kickstart installation](https://pykickstart.readthedocs.io/en/latest/kickstart-docs.html#chapter-1-introduction) method to deploy itself to a specific target computer or virtual machine.
> Phyllome OS is in its ***alpha*** stage of development. Expect bugs and disappointment
## The content of this repository
Each version of Phyllome OS is like a `dish` that is based on a `recipe` that lists `ingredients`, or basic building blocks for assembling Phyllome OS and other derivatives.
* `ingredients`🥑 🥥 🥭 🥝 🥦 🥬 🥒 🧄: Each ingredient represents a feature or a set of integrated features, such as a specific Desktop Environment
Example for the base storage ingredient used by Phyllome OS.
`cat ingredients/base-storage.cfg`
```
[...]
# What ? This kickstart file provides a basic ext4 unencrypted partition layout for UEFI-based systems
part /boot/efi --fstype="efi" --size=128 --fsoptions="umask=0077,shortname=winnt" --label=efi # Will create an EFI system partitition of 128 MiB (vda1)
part /boot --fstype="ext4" --size=512 --label=boot # Create a boot partition of 512 MiB using the ext4 filesystem (vda2)
part / --fstype="ext4" --grow --label=root # The remaining space will be used for root (vda3)
```
* `recipes`🧾 🧩: this directory contains recipes for deploying operating system artifacts on bare-metal, as a live system, or inside a virtual machine.
Let's take a look at the recipe to deploy Phyllome OS Desktop.
`cat recipes/desktop-hypervisor.cfg`
```
# What ? This kickstart file bootstraps a desktop hypervisor.
[...]
%include ../ingredients/base-fedora-repo.cfg # offical repositories for Fedora
%include ../ingredients/base-storage.cfg # base storage
%include ../ingredients/base.cfg # A minimal machine
%include ../ingredients/base-desktop-gnome.cfg # A desktop environment based on GNOME Shell
%include ../ingredients/base-desktop-virtual-machine-manager.cfg # the virtual machine manager
%include ../ingredients/base-hypervisor.cfg # A base hypervisor
%include ../ingredients/base-initial-setup-gnome.cfg # Includes initial-setup for GNOME Shell, allowing for the creation of a user after the first boot, as well as some basic configuration
```
* `dishes`🥨 🥐 🥖 🥧 🥞 🥯 🧆 🧁...: the end-product in the form of stand-alone and ready-to-consume kickstart file
Let's take a look at the final Phyllome OS Desktop dish.
`cat dishes/desktop-hypervisor.cfg`
```

## Development
Let's assume you wish to add [Luanti](https://www.luanti.org/), a free and open-source sandbox video game engine, as an ingredient to a dish.
* Clone this repository and move inside:
```
$ git clone https://git.phyllo.me/roots/phyllomeos && cd phyllomeos
```
* Make a copy of the `template.cfg` file and rename it
```
$ cp ingredients/template.cfg ingredients/extra-luanti.cfg
```
* Add software `luanti` to your file:
```
$ nano ingredients/extra-luanti.cfg
```
```
# What ? This partial kickstart file provides the video game Luanti
%packages --exclude-weakdeps # Beginning of the packages section. Excludes weak package dependencies
luanti # a free and open-source sandbox video game
%end
```
* Navigate inside the `recipes` folder:
```
$ cd recipes
```
* Pick a suitable recipe to add your ingredient to it. As luanti is a GUI application, `virtual-desktop.cfg` is a fitting candidate. Make a copy of it.
```
$ cp virtual-desktop.cfg virtual-desktop-lunanti.cfg
```
* Edit the file and add the newly defined ingredient:
```
$ nano virtual-desktop-luanti.cfg
```
```
%include ../ingredients/base-fedora-repo.cfg # offical repositories for Fedora
%include ../ingredients/base-storage.cfg # base storage
%include ../ingredients/base.cfg # A minimal machine
%include ../ingredients/base-desktop-gnome.cfg # A desktop environment
%include ../ingredients/base-guest-agents.cfg # Guest agents
%include ../ingredients/base-initial-setup-gnome.cfg # Includes initial-setup for GNOME Shell, allowing for the creation of a user after the first boot, as well as some basic configuration
%include ../ingredients/extra-luanti.cfg # A free and open-source sandbox video game
poweroff # Shut down the system after a successful installation
```
* Merge the kickstart basic building blocks a single file, or dish. This process is called 'flattening'.
```
$ ksflatten -c virtual-desktop-lunanti.cfg -o ../dishes/virtual-desktop-luanti.cfg
```
> If any errors are detected, go back and fix them.
If multiple dishes are affected by your ingredients, flatten them all while in the `recipes` folder.
```
for filename in *.cfg; do ksflatten -c "$filename" -o "../dishes/$filename"; done
```
* Navigate inside the `dishes` folder:
```
$ cd ../dishes/
```
* You can then kickstart your own installation:
```
